This invention relates to a loose leaf binder and concerns itself moredirectly with a metal hinge for hinging the impalingposts to the cover.i

It is an object of this invention to provide a hinge rod for the purposestated that has aV limited longitudinal movementv whereby the hingemember cannot be withdrawn from the covers and is susceptible of amovement that is not much more than suiiicient for unlatching theimpaling posts.

The invention comprises the novel structure and combination of partshereinafter described and more particularly pointed out and dened in theappended claims.

In the accompanying drawing which illustrates a preferred form of thisinvention and in which similar reference numerals refer to similarfeatures in the different views:

Figure l is a perspective view of a loose leaf binder involving thisinvention.

Figure 2 is a fragmentary end elevational View of the same;

Figure 3 is an enlarged interior fragmentary plan view.

Figure 4 is an enlarged fragmentary inte rior plan view of one of thehinge plates showing parts in section.

This invention is applied to'a binder consisting of a cover comprisingthe side members l and a rear member 2 which may be integral with theside'portions. A hinge plate 3 is attached to the interior side of, and.

on the margin of each side member adjacent said back member, and thisplate is provided with a coil or tube 4 for receiving the latchingmember 5. VThe tubular terminal of each plate 3 is provided with spacednotches or recesses 6 for receiving the ends of the impaling posts 7.The tubular terminal of each plate 3 is also cut away as indicated at 8for a purpose that will later appear. Y

The latching member 5 Vconsists of two jointed rods 5a, and 5b'. The rod5a has oner purpose of spanning the adjacent post recess 6. Y

- The rod 5b has an offset portion 5d thatlei Y the coil 4 tothe end ofthebinder whereit l is folded over providing a pintle arm 5c thatextends into the tubular terminal for spanning the third post recess 6.The folded portion of each latch member is preferably bent inwardly toprovide a handle as shown in Figure 2.

. In Figure 4, the latching member is shown in retracted position inwhich the pivoted end 10 of the rod 5a abuts the shoulder 11 forming thenear end of the first recess 8. The

end 10 and the shoulder 1l serve as coacting stops for limiting thewithdrawal ofthe latch member. When the latch member. is

longitudinally pushed inwardly, the offset pintle portions 5c, 5d, and5e will span the recesses 6 and pierce the openings in the impalingposts 7 as is usual in the art;

It will be appreciated-that according to this invention, it is onlypossible to withdraw :the hinge Vmember a short distance so itcannotvbecome lost or distorted. VBesides abetter and stronger postpintle can be provided.

I am aware that many ychanges may be made and numerous details ofconstruction" maybe varied through a wide range without departing fromthe principles of this invention, and I do not therefore purposelimiting the patent granted hereon otherwise than necessitated by theprior art.

I claim as my invention:

l. In a loose leaf binder, a cover member, a plate having a notchedbarrel attached to said cover member, a slidable latching section onsaid plate and having an offset pintle at one end for entering saidbarrel, said bar-y rel having a slot forming a shoulder for arrestingthe otherend of said latching section, and another latching sectionconnected to the first section and having pintle portions extending intosaid barrel. y 2.
